Claims16
A reservoir for use with a spray apparatus, comprising:
- a body including a first end portion having an outlet, a second end portion having an inlet, and a passageway extending between the inlet and the outlet, the first end portion including interior threads disposed within the passageway configured to be threadly coupled to a threaded coupling member of the spray apparatus and exterior threads of a plug, the first end portion including a radially extending inward portion in the passageway;
- and
- a lid removably attachable to the second portion to cover the inlet, the lid having a vent therein communicating with the passageway when attached to the body and a wall extending about the vent defining a plug receiving space, the wall having interior threads sized and configured to be threadly coupled to the exterior threads of the plug, the threads of the passageway and the threads of the plug being configured to allow at least a portion of an end of the plug to abut the radially extending inward portion of the passageway when the exterior threads of the plug are threadly coupled to the interior threads of the first end portion of the passageway.
A method of using a reservoir having a first end portion having an outlet and a second end portion having an inlet, and a passageway extending between the inlet and the outlet, comprising:
- threadly coupling a first plug to interior threads of the first end portion of the reservoir to obstruct the outlet of the reservoir, an end of the first plug abutting an inward extending radial portion positioned on an inner surface of the first end portion of the reservoir;
- pouring one or more liquids through the inlet of the reservoir and into the passageway of the reservoir;
- attaching a lid to the second end portion after the act of pouring one or more liquids;
- and
- threadly coupling a second plug to interior threads of a plug receiving portion on the lid to obstruct a vent formed in the lid, an end of the second plug abutting an outer surface of the lid.
